I've got very thick, coarse hair. I wash it just once a week and straighten with GHD's. I run the straighteners through my fringe everyday. If left to dry naturally it puffs up, frizzes, sort of curls but generally just looks a bit mad. I'm going on holiday this weekend and will be spending my time sat round a pool in very hot and humid conditions. I'll be in and out of the pool so what do I do with my hair inbetween dips? Does anyone have any tips for something I can spray on it so that when it dries in the sun the frizz and puffiness is minimalised? I've been considering sea salt sprays, leave in conditioners, oils but don't know if any of these will help. Or is my only option a hat?
